“New YorK AGRICULTURAL EXPERIMENT STATION, 119 
over, the two Rhizoctonia-infested plants were potted and placed 
in one of the Station greenhouses where they thrived and never 
after showed any ill effects from the presence of the Rhizoctonia. 
About a year after this experience, interest in the violet 
Riiecctonia was revived by Mr. Rolfs’ discovery of a case of de- 
structive violet stem-rot in a greenhouse at Geneva.’ Here the 
affected plants were abundantly infested by Rhizoctonia.. At 
about the same time we found it on violets at Floral Park. The 
plants were in small pots. Some of them had stem-rot!, while 
on others only the bases of the petioles were rotten. The rotten 
parts frequently contained Rhizoctonia. 
Thus it appears that Rhizoctonia occurs not infrequently on 
violets, but whether as a parasite or only as a saprophyte can 
not now be stated. 
OTHER HOSTS. 
In addition to the occurrence of Rhizoctonia ag an apparent 
cause of diseases of the host plants already mentioned, there are 
several] other plants upon which we have occasionally found this 
fungus. For the sake of brevity, we will condense the observa- 
tions upon these, and bring them together under a single head- 
ing, deferring their more extended discussion until further ob- 
servations and studies have been made upon them. 
Rhizoctonia has been found on the roots and trunk of a dead 
cherry tree from Wright’s Corners; as a damping-off disease of 
white pine and cucumber seedings; on damped off cuttings of 
begonia, coleus, verbena, hydrangea, hardy candytuft, and mam- 
moth sage at Floral Park, N. Y.; on mature plants of ph'ox and 
pyrethrum at Floral Park; and on young plants of snap dragon 
at Geneva. Mr. Rolfs has observed it on the raspberry, lamb’s 
quarters (Chenopodium album), tumble weed (Amarantus albus), 
pigweed (Amarantus retroflerus), and on decaying squash stems at 
Geneva. .

*Violet stem-rot is a complex disease not well understood. The fungus 
Thielavia basicola Zopf is generally accepted as being the cause of it. See
